When SMS saves a project, all the data related to coverages in the Map module is written to a single ASCII file named proj_name.map.
Although this file is ASCII and can therefore be read in a text editor, it's recommend that a user not edit these files. It's also not recommend that a user develop utilities based the current format of these files. The format has changed between versions of SMS, and although SMS maintains backward compatibility to read older file formats, there is no guarantee that older formats will be written by future versions of SMS. In fact, the ASCII file may not be maintained at all.
